Lean Process Design of High-strength and High-conductivity Copper Alloy Contact

The work aims to improve such deficiencies as low material utilization ratio, long production cycle and high energy consumption, so as to reduce the costs of products manufactured. Based on analyzing structure features, technical requirements and processing technology of high-strength and high-conductivity copper alloy contact, the lean design and process test of the original manufacturing process were conducted with the advanced technology and methods, such as on-line solution of copper alloy and precision forging. By adopting the process plan after the lean design, the quality of the products experimented was stable, the energy consumption was reduced, the production cycle was shortened and the utilization ratio of materials was improved. The process plan, through popularization and application, has been proven to be economical and practical and meet the operating requirements of mass production.
